LOCK FOR STORM SASHES Filed July 11, 1952' BY w A M' Patented Sept. 15,1953 4UNITED STATES PATENT OFFICE LOCK FUR. STORM SASH Irving H.Schwartz, Philadelphia, Pa. Application July 11, 1952, Serial No.298,328

2 Claims.

1 f l Storm windows of the self storing type include a triple trackattached to the window frame and in which are adapted to be slidablymounted the usual inner glazed sash, outer glazed sash, and the screenedsash. Also retaining means are provided for retaining any of said sashesin any position to which it may be moved.

One object of my invention is to produce an limproved sash retainingdevice whereby the sash may be locked in any position to which it isadjusted.

A further object is to produce an improved sash retaining device whichis light, inexpensive, and easy to operate.

A still further object is to produce a sash retaining device which iscarried by, and movable with, the sash and which frictionally engages awall of the track in which such sash slides.

These and other objects are attained by my invention as set forth in thefollowing specication and the accompanying drawings in which:

Fig. l is an elevational view of a window the lower, inner, sash ofwhich is provided with a sash retaining device embodying my invention.

Fig. 2 is an enlargement of the bracketed portion of Fig. 1.

Fig. 3 is an enlarged sectional view looking in the direction of line3-3 on Fig. 1.

Fig. 4 is a fragmentary side elevational view of the storm sash frameshown detached, with the retaining device omitted.

Fig. 5 is an enlarged transverse, sectional View looking in thedirection of line 5-5 on Fig. 4.

In Fig. l there is shown the inner, or room side,

of a wall of a room which is provided with a window opening of the usualtype. The window opening is closed by means of the usual, inner andouter, vertically slidable, glazed sashes which are conventional instructure and operation and are therefore not shown nor described. Forthe purpose of this invention, it is merely necessary to refer to theconventional window frame, or to the wall defining the window opening,regardless of whether such wall be of wood, of masonry, or of otherconstruction, as the window frame |2.

In order to adapt the window frame to a standard size storm sash, anadapter I4, of a generally U-shaped cross section, is secured to thewindow frame by means of screws or the like, not shown. The limbs i6 ofthe adapter frame are adapted adjustably to receive therebetween theinner and outer walls and 2| which form part of, or are carried by, thestorm sash triple track to be later described. The

walls 20, and 2|, or either of them, is suitably secured to the limbs I6of the adapter frame I4 by means of screws or the like, not shown. Bythis construction, the window opening, or the window frame I2, isadjusted, within reasonable limits, to receive a standard size stormWindow thus making it unnecessary to fabricate the storm windows in manysizes and to close tolerances. The construction described alsofacilitates the mounting of the storm windows.

The inner ends of the walls 20 and 2| cradle between them an abutmentwall 22 which serves as a backing for the Wall 24 of the sash receivingtrack. The track itself is formed of inwardly projecting walls 26, 21and 28 which, in cooperation with the extension 29 of the outer wall 2|of the adapter frame, define channels 33, 34 and for respectivelyreceiving the frames of the inner and outer glazed sashes and thescreened sash.

The frame of the storm sash itself includes a body portion 36 the innerside of which is provided with a relatively narrow channel 38 forreceiving the edge of the glass 39 and with a relatively large channelprovided with gaskets 40 for engaging the marginal portion of the glassin a cushioned and tight manner, as best shown in Fig. 3. The oppositeor outer, side of the sash frame is provided with a channel 42 forengaging one of the walls 26, 21 or 23. It will be noted that the edgesof the walls defining channel 42 converge as at 43 so as to have a linecontact or bearing on the wall 26, 21, or 28 engaged thereby and thusreduce friction and the tendency to bind.

The sash retaining device of my invention includes a plate-like member aportion 44 of which is adapted to engage the inner face 45 of the sashframe, and the inner edge of which is bent outwardly as at 46 so as toengage the inner edge 41 of the sash frame. The plate like member alsoincludes a dished portion 48 from which is struck an outwardlyprojecting tongue 66 and the outer portion 52 of which is adapted toengage the inner, or room side face of adapter wall 20 as at 5|. Thewall 20 of the adapter frame is provided with a marginal notch or hole54 through which tongue is adapted to pass to engage the inner, o1' roomside, face or wall of the track 28. See Fig. 3. The retaining devicealso includes a bolt or screw 56 which is adapted to pass through anopening 51 in the dished portion 48 and to engage a tapped opening 58 inthe body 36 of the sash frame.

When it is desired to raise or lower the storm sash 60, the screw 56 isbacked oi until the tongue 50 is disengaged from notch 54. When the sashhas been moved to the desired position, the screw 56 is tightened toforce the tongue 50 into tight engagement with track 28 and to force theouter, or right hand portion, of the dished member 48, as viewed in Fig.3, into tight engagement with the room side of wall 20 of the adapterframe as shown at 5I. The sash is now locked tightly in position.

It will be seen that the retaining device is small, light, compact andinexpensive, that it is easy to operate, and that, being carried by thesash it can not be mislaid. Also, the part of the retaining device whichengages the track 28 or the wall 20 does not have to enter a slot orhole but can engage any portion of the fixed surfaces' which correspondto the position of the sash. It will also be seen that the contact, at5I, of the long edge (see Fig. 2) of the portion 52 of the retainingdevice, and; the contact of tongue 50 with track 28, produce a stableengagement sufcient to prevent rattling or slipping of' the sash.

What I claim is:

1. For use in connection with window construction of the type whichincludes a window frame, an inwardly projecting track carried` by saidframe, a sash for closing the Window opening, and a pair o f outwardlyprojecting walls defining a channel for receiving said track with saidwalls disposed alilrlg` the opposite sides of said track, a lock forsecuring said sash to said window frame, said lock including a plate, atongue projecting from said plate in the direction of said track, therebeingy a passage formed in the adjacent one of said pair of wallsthrough which said tongue is adapted to pass to engage said track, saidplatehaving an` opening therein and said sash frame having a tapped holetherein, and a bolt having a reduced portion adapted to pass through theopening in said plate to engage said tapped hole and having an enlargedhead adapted to bear on said plate to press said tongue against saidtrack.

2. For use in connection with window construction of the type whichincludes a window frame, an inwardly projecting track carried by saidframe, a sash for closing the window opening, and a pair of outwardlyprojecting walls dening a channel for receiving said track with saidwalls disposed along the opposite sides of said track, a lock forsecuring said sash to said window frame, said lock including a plate, ofa size suiiicient to overlap at least a portion of the window frame andat least a portion of the sash frame, a tongue projecting from saidplate in the direction of said track, there being a passage formed inthe adjacent one of said pair of walls through which said tongue isadapted to pass to engage said track, said plate having an openingtherein and said sash frame having a tapped hole therein, and a bolthaving a reduced portion adapted to pass through the opening in saidplate to engage said tapped hole and having an enlarged head adapted tobear on said plate to press said tongue against said track and to presssaid plate against said sash frame and against said window frame.
